The appearance of this invention. is suitable to allow its use in a varied number of places. It is designed to provide a rigid and self-sustaining permanent shade which should be mounted in concrete. The objective of the louvered top is to decrease wind forces against the structure and to allow ventilation of heat. Other definite objects of this invention are that it is simple, it can be easily prefabricated. and it can be easily assembled with fasteners (in respect of its relatively large size) at the place of installation.

Other advantages and objects of the invention will be obvious during the course of the following specifications.

In the accompanying drawings, forming a part of this specification,

FIG. 1 is a side elevation view of the Dyna-Shade,

FIG. 2 is a plan view,

FIG. 3 is a section taken on line 33 of FIG. 2,

FIG. 4 (for optional construction) is a section on line 4-4 of FIG. 3,

FIG. 5 (for optional construction) is a section on line 5-5 of FIG. 3,

FIG. 6 is a section taken on line 66 of FIG. 3,

FIG. 7 is an orthographic projection from FIG. 6,

FIGS. 7a, 7b, 7c, 7d, 7e, and 7fare illustrations of optional shapes relating to FIG. 7,

FIG. 8 is a section taken on line 88 of FIG. 3,

FIG. 9 is an exploded oblique in part of FIG. 3, and,

FIG. 10 is an enlarged detail related to FIG. 9.

Referring to the drawings, the supporting one-piece column 11 should be inserted in concrete as shown in FIG. 3. A bracket 11a is welded to the column 11, a bracket 11b is welded to the top end of the column 11 and a threaded nut 11c is welded to 11b. For optional construction the supporting column 11 may be made of two separate pieces with a sleeve Ild welded to the upper portion of 11 and connected to the lower portion of 11 with fasteners as illustrated in FIG. 4 or it 11 may be made of two telescoping pieces connected together with fasteners as shown in FIG. 5.

The strut frame 12 is a weldment containing 12a, 12b, 12c, 12d, and 12e thus forming a plurality of offsets along its upper portion. For optional construction and the strut frame 12 can be an assembly having its parts joined together with fasteners as illustrated in FIG. 7e. The quantity of braces 12d and I2e required in each strut frame 12 is dependent on the overall length of the strut frame 12. The length of the strut frame 12 is dependent on the quantity of offsets 120 to be used (FIG. 7 Ref.) and the length of strut segments 12a and 12b.

The lower portion of the strut frame 12 is connected to bracket Ila with a fastener, the upper portion (strut segment 12a) is slotted to slip over the top end of the wall of the column 11, the slotted bracket 11b locates and holds strut segment 12a in the proper place (FIG. 9 Ref.) and the apex cover acts as a retainer. A plurality of strut frames 12 are equallyspaced completely around the column 11. For increased bracing the strut frames 12 are all connected together with brace members 13 and fasteners. To increase stability, lateral brace members 14 are connected to bracket 11a and strut frames 12 with fasteners.

The cover is broken into a plurality of levels and consists of a plurality of segments in each level. All covering segments l5, l6, 17, 18, and 19 are attached to the upper portion of the strut frames 12 (strut segments 12a and 12b) with fasteners. The quantity of covering segments in each level of the cover is equal to the number of strut frames 12 used. All covering segments of each level have a common size, shape, and hole pattern which matches the hole pattern in the respective levels of the strut frames 12. The longitudinal edges of the covering segments 15, 16, l7, l8, and 19 overlap above the strut segments 12a and 12b as shown in FIGv 6.

The physical shape of the covering material is thin and flat as shown in FIG. 7 or it may be corrugated as shown in FIG. 7f. With exception to the inner end of the top level covering segments 15, both ends (inner and outer) of all other covering segments may have optional shapes conforming to those illustrated in FIGSv 7a, 7b, 70,711, and 7e.

The apex portion 20 of the cover is a conical disk (of thicker and stronger material than the covering segments) with a hole in its center and a pitch that coincides with the pitch of the cover. A screw 21 is placed through the hole in the apex cover 20 and screwed into a threaded nut 110. The screw 21 is tightened against the apex cover 20 to form a compression type retainer for the inner ends of covering segments l5 and the upper portion (segment 12a) of the strut frames 12.

Having thus described my invention, I claim:

1. An umbrella-shaped shade-providing structure, comprising: 4

a central column adapted for attachment in the ground on the like;

a plurality of first radially extending frame members and a first column mount means mounting said first radially extending frame members onto said column;

each of said first radially extending frame members sloping downwardly from said first column mount means;
